Is there a limitation on the maximum to upload via FTP? Anyway to increase the limit?
Maximum file size can be limited by FTP quota.
FTP quota table can be checked using the following command:
# /usr/bin/ftpquota --show-records --type limit
ftpquota: unable to open ./ftpquota.limittab: No such file or directory
The command output above shows that FTP quotas are not configured and maximum file size is unlimited.
